Comcast said on Wednesday it plans to spin off some NBCUniversal cable TV networks, as the rise of streaming prompts the media company to relinquish some of its most prized assets.

Comcast said Wednesday that it is planning to spin off its NBCUniversal cable TV networks, including channels like MSNBC, CNBC, and E!, carving out a business that has been hurt by cord cutting and the rise of streaming.

Comcast is moving forward with the spinoff of its cable networks, including CNBC, MSNBC and E!. The spinoff is expected to take about a year, according to a company memo. Bravo is not part of the spinoff.
